Add interactive mode to `magpie init` allowing users to select which AI
reviewers to configure. Shows available options with API key requirements
and generates a customized config. Supports -y flag for defaults.
Add --local flag to `magpie review` to review uncommitted changes (staged
+ unstaged) without needing a PR. Falls back to last commit if no local
changes exist.
